android-file-transfer-linux: depend on libmtp-udev (newly split)

[dkwo]

it's missing udev rules

• I tested the changes in this PR: yes

@dkwo Im unable to test as I use other means to mount.
If adding libmtp as a dependancy and that works I would venture creating a extra libmtp symlink to -ng, however it makes conflicts with other packages. Question remains why the fork.

[dkwo]

@tornaria does it make sense to you?

[tornaria]

What is this supposed to solve?

[dkwo]

libmtp also ships some udev rules that are useful to other packages using MTP, e.g. android-file-transfer.
we split those in a subpackage, and make aft depend on it.
without this, one cannot use e.g. aft-mtp-mount (not even after installing android-udev-rules).
with this, it is enough to be a member of plugdev group.

[tornaria]

I see. Your solution seems reasonable.

A simple workaround meanwhile is to install libmtp when one needs this.

[dkwo]

@leahneukirchen Can you look at this one as well?

[Duncaen]

The split doesn't make sense when the split out package depends on libmtp anyways (usr/lib/udev/mtp-probe links libmtp.so.9).

[dkwo]

I see, you're right.
